for adjusting the ball bearings for the sliding framework. Fixed to the frame 48 are two vertical grooved guide bars 51 (Figs. 7, 10 and 12) in which is mounted a slide 52, to which slide the dotting tube 4- is attached. The donning tube 45 and the bobbin-seater 46 are attached to the sliding framework.

The means herein shown for reciprocating said framework horizontally with relation to the carriage, and for \ertically reciproeating the slide 52 with relation to said framework comprises a' cam disk wheel 53 (Figs. 2, 7 and 10) secured to :tdie rear end of the shaft 36. In one face of said wheel is a cam groove 54 to receive a roller stud 55 carried by the sliding framework; and upon'its opposite face is a roller stud 56 (Figs. 10 and 12) fitting in a channel bar 57 secured to theslide "The weight of the slide 52 and the parts ca r ed thereby is counterbalanced by the wsighz-portion 58 of the cam wheel. The contour of the cam grooye 5i is such that the sliding framework is stationary with reference to the spinning frame whilea filled-bobbin is being iemoved, and is then given a quick forward movement to place the dotting tube, the donning tube and the bobbin-seatcr in register witn suc- The devices that engage the filled bobbins to remove the same from the spindles consist, in the present embodiment. of dogs 59 (Fig. '19) with eccentric toothed gripping faces, said dogs being pivotally mounted between cars (30 upon a bracket (31., b'aid bracket is fixed to-the slide '52. The dogs 52) extend throughslots in.the dolling tube 44, the inward movement of said dogs being limited by the bracket 61 or by engagement with a filled bobbin, while the upward and outward inorcment of the dogs is restrained bya coiled .sprin (52. When the tube 44 descends over a dlled bobbiii, the dogs 59 yield outwardly, and on th upward movement of the tube the dogs grip the bobbin and cause it. to rise with thts tiibei- .Thc. latter serves the purpose of a conduit or guide through which the dofi'ed bobbins are conducted away from the bobin-cngay ing means 59, as will appcar hereinafter. lho forward side of the upper part of the tube is cut away, as indicated in Fig. ii. to prevcnt interference with .a flaring bobbin- 7 guide (33 fixed to the structure 47 48 in line bobbin.

Piroted to the llClC 52 at 67 Fig. 12) is a finger (5S projecting toward the center of the tube 4. said finger being arranged to yield upwardl against the tension of a spring till (Fig. 10), the operative position of the finger being determined by the contact of the shoulder T0 with the slide 5'3.

The operation of the bobbin-rcmoving dcviccs may be'bricfl described as follows: The tube -H descends over a filled bobbin. 'hcn the tube rises the dogs 59 cause the bobbin to be pulled off its spindle. the tube in its upward movement carrying the doti'cd bobbin into the space between the dogs (35. The sliding framework is thcn given a quick horizontal movement to carry the tube into position above the next succeeding tilled bobbin. When the tube starts to descend upon said succeeding bobbin. the bobbin that was lifted into the space between the dogs 65 is gripped and retained by said dogs in the position occupied bv the upper bobbin in Fig. 12. \Vlzcn the bobbin is thus retained by the dogs (35, the finger 38 swings aside as the tube 44 and slide 52 descend. and snaps into position bcncath said bobbin when the finger has passed the bobbin. Upon the next upward movement of the tube and slide. the linger (i8 pushes the upper bobbin into-the bobbin-guidc (53, the curvcd form of the upper 'wall whereof cau es the bobbin t tiltand be discharged into the flaring upper end of a vcrtical guide tube 71. From the guidev tulait. the bobbins drop into the bo.\ (i.

Means is provided for scrcring the yarn extending from the drawing rolls to the bobbius.- In this instance. the \'arn-cutting incans is mounted to travcl with the dolling tube. and is arranged to be actuated through relative movementbetween thccutter-sup ort and the tube. The cuttcr support consists of a bracket 72 fixed to a tube 73 telescoping slidably with the tube 44. .\t-thc forward side of said bracket is a guide. arm 74 (Fig. 1:!) having two fingers T5 thcrcoii arranged ttr slidc at either side of a guide Tl) fixed to tlnislidc 5:2. it will be sccn that the parts 74 and T0 scrvc to prevent rotation of the tub 73. coiled spring 77 tends to move the bracket 7:! downwardlv with relation to the. tube -l-l to thc extent permitted by contact. of the lingers 75 with the lower end TS of the guide To. ()1: the lowcl' side of the bracket 7;! are two pins 79 arrangct to strikc against. the ring rail as the dolling tube 44 dcsccnds and thus sup iort'tho cutter-sup port at a suitablc height with irfcrcnce to the yarn to be sheared.

'lhc cuttcr comprises a blade Ht) (Fig. 1(3) lixcd to a lug 81. on the brackct- T2. and a blade 8;! piv ted at 834m said lug. spring 84 acting upon an angular cxtcnsionSfi of the blade 52 tends to swing said blade to open the shear. The shear is closed by a cam v I site directions; that ist-o 8 carried by the slide and arranged o engagia projection 87 on the pivoted blade in this instance. the cam 86 is inonntcijl for horizontal adjustment-on a bracket S8 which in turn is arranged for vertical adjustment. on the slide (Figs. 16., 1F and 18). .is the tube 4% descending the pins 79 strike the ring rail and thereby arrest the downward movement of the shear support. Continuing movement of tho slide 52 and the tube 44 brings die cam so into engagement with the pri'ijcctior. on the shear bflide 82., whereby the shearis ar-tnatcd to so ver the tlircad loading to the bobbin last d lled. T2 is a guard liar-d lo the bracket 72 in position to overlie {hriln'rad in be cur. The guard 13 insuros an invariablc position of the thread when ln in; out. and thus provides a fixed time for llu-rntiing ofilic thread.

Tho donning tube. 45 is rigidly fixed to the sliding framework parallel to the path of rcrtical reciprocation of the dofiing tube A. At the open lower end of the donning tube are two spring detcnts 89 adapted to rclcasably support an empty bobbin between them. In order to force a bobbin past said. spring dctcnts so that it shall drop onto the bare spindle above which the donning tube is positioned at the time, I provide suitable means. as, for example, an ejector 90 (Figs. 10 and 15) pivoted at 91 on a bracket- 9:2 fixed to the slide Z32, said ejector extending through a longitudinal slot 93 in tliedonning tube. Pivotal movement of the ejector in one direct-ion is limited by the contactof the rear end lll of said cjector with the bracket 92. Pivotal movement in the opposite direction is yicldingly resisted by a spring 95. lVbcn the slide 52 descends, the jcctor 90 expcls the bobbin fi'on'rtlietube 45, said bobbin dropping onto the bare spin dlc which is alined with said 'tube: llhen. She slide 52ngain dcsccnds (said slide hav ing meanwhileadvanced horizontally a dis tance equal to the distance between two ad jacent spindles .brough a horizontal m0rementof the sliding framework) the donncd bobbin is forrcd firmly to place on its spin dle by the bobbin-scatcr 4?, said device consisting in this instance of-a spring arm secured to the channel bar 5?.

Empty bobbins to take the place of those dofi'ed in the operation of the machine may be carried in a magazine 96 shown in from elevation in Fig. 13 and in side elevation in Fig. 22. In fibeibrm herein shown the magazine is a rectangular receptacle arranged to contain a number ofvertical tiers of bobbins, the tiers being'keptdistinct by short vertical partitions 97 (Fig. 26). The bobbinsof :1 tier extend alternafely in opposay, the tip of one bobbin extends in one direction, while the .tip of like. next bobbin of the tier extends in opposite direction. It will also be apparont from Fi 27 that the bobbins of a given horizontal layer extend altcrnaiely in opposite directions. The butts of tile bobbins lie between the partitions'97, and the of the bobbins are held against lateral displacement by being disposed within vertical slots 98 in the side wallsof the magazine. When the doll'er is in use, the lower end of the magazine is open, but while tho magazine is being filled and handled separately from the dollar, its lowercnd is closed by suitable means, such as a wire bail 923. the two horizontal arms of which a adapted to lie in notches lG-J and openings 103. in the lower edges of tin. magazino mills and parzitions. Said bail is removably held in place by a laich 102 pivoted at 1 3 so char it may be turned into and out of position to overlie the bail, said latch having a finger portion or handle 104. i

The magazine- 96 is rcmovably secured upon t'n'o bars 105 (Fig. 2 1) fixed toa framework 106 carried by the top bracket 15; said bars having notches 10? there-in with which the slots 98 of the magazine register. In this instance the magazine is relcasably attached to its support by means of several devices. to wit, two rigidangula'r stops 108 fixed to the framework 106 and adapted to overlic a band 109 extending about the lower. end of the magazine, said stops engaging ihc rear side of the magazine; two rigid.

gnidcs or stops 1-10 arranged to prevent lat oral displacement of thcinagazine; and two spring can-lies 111 adapted to snap over the band 109 at the front side of the-magazine.

in operation, the bobbins in tlievvn'iagazine rest upon a bobbin-fccding incans located below the. magazine and virtually forming the bottom of the latter. In the present embodimcnb. said bobbin-feeding means consists of a conveyor formed of two cndloss chains 112 mounted upon sprocketwhcels 1'13, two bf said \vliccls 115, said sbafts being supported in the framework 106. In order' tliatslack in the being mounted upon a. shaft 114-, and the other two upon a shaft chains may be taken up. the framework 103 I is formed of arear brackot'UXl rigidly at tocbcd to the number-'15; and'a front bracket lfiil -adjustably secured at 116 ber 15. The from; endsjof the to said mold; v bars 105 lire adjnstablr fiscd 'tothe bracket 106 rated at 1'17. r

Each of the chains 112 has fixedthereto lugs 118 forming between them recesses 119 are held fronr 'up'i lard displacemcntby guard rails 122 (Figs. 24 and 25).

other reccsseslQO adapted to su pporb the I The conveyor-is driven through a spiral 20 man whereby dell' r and a g-lowerends of to a magazine 96 is placed upon the dolfer; and

- -..tl 1e topso f the lugs. The crank is then no unlocked and operated until the bobbin ,con-

gear connection (123 124) between the shut 115 and a vertical shaft 125 geared to the shaft 36.

At the discharge end of the conveyer is a 5 hopper 126' having downwardly converging walls, the open lower end of which hopper is arranged immediately above'the flaring inlet end 127 of the donning tube 45. Above the hopper 126 and directly opposite the discharge end-of the conveyer is a guard plate 128, and at the sides of the discharge ends of the conveyor are other guard plates 128". A rod 129 extends across the space between the conveyor and the guard plate in a direction transverse to the len h f the bobbins and midwa of the wi th f the conveyer. When t e bobbins discharged from the conveyer fall upon the rod 129 the butt ends of the bobbins swing downthe bobbins are caused to enter the ho 'per 126 butt-end first. From the hopper t e bobbins drop into the don- 'nin tube, the ejector 90 yielding to permit the bbins to pass it, and each bobbin bein arrested by the spring detents 89 and he d there a moment until the ejector forces it out of the donning tube.

It'will be seen that gravity is employed to transfer thial fromthe, hgrizonltal so'pfiltron w i ey occup w en; is charged to the vertical posi tio'n required prevwusto donning, mechanism forgiving the bobbins an upright osit'ronbeing thus dispensed with. It will also be seen that 86 the use of grayity isparticularly advantafileous where the bobbins are stacked with rge and small ends alternating, as herein shown e The bobbin-conveyer is arranged to dis tq'char ge thebobbins at the" rear .side of thesubstantially directly above the donning point, This arrangement is advimta'geous where the bobbms arestored with butts and tips alternating, as each bob- 46' bin travels an equal distance in assing from the conveier to the donning tu s 45.. t e bobbins u'pona spinning frame -a're-ready to be defied, the ring rail e is in its lowermost position, and ajoin-turns of yarnare fspun aroundthethe bobbins. The spinning is then pod, and the thread'board ffi thrown back. x f The crank 37 being in its locked position,

ball- 99 removed from said magazine, whereupon the bobbins settle in the maga: .zme until the lowermost bobbins rest upon and the donning jsupplied with bobbins. It will'be seen that a":m'ovement'-of the-conreyer equal to ofitha hein i lm llia 191 m.

tube are properly tube descends u bobbins to slip into the recesses between the lugs 118 on the upper side of the conveyer, and that in the continued travel of the convey er the tiers of bobbins will he exhausted successively beginning with the front tier (the left-hand tier in Fig. 2

The conveyer and the donning tube having been supplied with bobbins, the crank 37 is again locked in the position shown in Fig. 1, wherein the mechanism is in its initial position, with the dofiing tube elevated, and the dofi'er placed in operative relation to the spinning frame, the lower carriage-section being clear of the floor, the upper carriage-section being supported upon the rail 28, and the two sections locked together. The dofi'er may now be actuated and fed continuously alon the spinning frame by operating the cran 37.

As the dofling tube 44 moves downward overa full bobbin, the dogs 59 swing outwardly upon their pivots to pass the bobbin. On the upward movement of the tube, the dogs engage the yarn on the bobbin and cause the bobbin te' ',rise with the tube into the space-between the dogs 65. \Vhen the pen the next bobbin the first is retained by t e dogs 65, to be ejected by the member 68 on the next upward move ment of the tube.

Referring now to Fig. 11: As the bobbin is lifted ofi its spindle by the dogs 59, a few wraps of the thread that was wound upon the lower end of the bobbin sli'p from the bobbin onto the spindle, as shown in Fig. 11, so that when an empty bobbin is placed on the spindle the thread will be caught and held by it. As the sliding framework 47 48 is moved forward with relation tothe spinning frame, the dotting tube is moved into position over the next adjacent bobbin, the wedge-shaped portion 72* of the bracket 72 (Fig. 18) insuring by its'plow-likeaction that the thread running to said bobbin shall not catch upon the upper end of the bobbin and be broken. When the dofiing tube is lowered onto the last mentioned bobbin, the thread portion 9 running from the previ ously defied bobbin to the spindle from which it was removed enters the shear 80 8'2 and is severed as the dofiing tube completes its downward movement.

The foregoing detailed description has been given for the sake ofclea-rness of disclosure only, it being understood that the embodiment described is susceptible of considerable modification without departure from the spirit of the invention.
